Radiant Heating & Cooling

Chiltrix is widely used in radiant heating applications as the source or “supply side” that a radiant system plugs into. In addition to the well-known advantages of radiant heating, radiant cooling works well in many applications. Contact us for a comprehensive radiant heating and/or cooling evaluation.

Another Broken Record

In addition to holding worlds records for space heating and cooling efficiency, Chiltrix also holds the record for the highest certified UEF (Uniform Energy Factor) for domestic water heating, including all heat pump water heaters. UEF is the official US DOE metric for water heater efficiency.

Leading the Industry

What sets Chiltrix apart

We are not a marketing company. And what really sets us apart from competitors is our never-ending pursuit of R&D and product excellence. With 60% of our team composed of engineers, Chiltrix's goal with every product is to design, build, and properly support the most rugged, reliable, and efficient products on the market, without cutting any corners. We use only top-shelf components sourced from the best manufacturers in the world, resulting in higher build quality than competing products.

Our mantra is that while conservation is the goal, it must never result in deprivation. As Americans, we know the American consumer is the most demanding in the world – we know what we want, and we want it now. So, we design and build with the American consumer in mind. If we can satisfy the American consumer, then we can satisfy any customer worldwide.

The Chiltrix small air cooled heat pump chiller compressors are fully variable in capacity and operation is continuously adjusted to match the required heating or cooling output, avoiding on/off cycling and wasted energy. When measured on an annual basis, the average energy savings produced by the Chiltrix dynamic capacity and control system can exceed 50%.

Chiltrix includes a variable speed DC pump for the supply side circulation. When full water flow is not needed due to off-peak capacity requirements, the water pump slows down and uses less energy. The variable speed pump and variable speed compressor work in tandem with the system controller using a special algorithm to keep the compressor and pump both working at the optimum speed. The variable speed condenser fan is controlled in a similar manner. This allows all of the consumers of electrical power within the chiller to operate at the lowest power level to meet the current load. Dynamically controlling the water pump speed and compressor speed independently of each other helps us to achieve the highest levels of performance. In addition, Chiltrix offers DC-Inverter indoor fan coil units, further reducing electrical power consumption (along with lower sound levels and longer lifespan).

Working together, the variable speed compressor, variable speed pump, variable speed condenser fan, and variable speed indoor units all operate at the most efficient level of power consumption possible to meet the demand. From 25% to 100%, the system is always exactly the right size for the job. Under varying real-world conditions the Chiltrix air to water heat pumps can efficiently operate at the capacity needed and can achieve up to 50% or more in electrical savings each year compared to others.

The Psychrologix™ psychrometric chiller controller dynamically manages humidity and automatically adjusts the parameters of the heat pump chiller in real time, for an off-the-charts increase in efficiency (above its already high rating) when dehumidification is not needed. DHC (Dynamic Humidity Control) can automatically lower the indoor unit coil temperatures to quickly remove any humidity increase. When humidity is within acceptable limits, the system will dynamically reconfigure itself to the most efficient possible operating parameters allowing the chiller to run well above its rated efficiency. The Psychrologix™ chiller control option can manage up to three chillers. See the Psychrologix™ DHC controller details here.
